adc~ has no signal when monitored with [env~] or [pvu~] --> [vu].
The internal microphone works. Audio drivers on Pd are set to take Built in microphone 2 channels. Audio and Midi drivers (on a Mac) is set to use internal microphone. I've used system preferences to test/playback mic input.
Other sounds work in Pd. DSP is on/computing. I tried listening for anything despite the visual showing that it wasn't working -- with headphones. I'm at a loss. Any help here is appreciated.
